Winsock2.pas源码，开发网络编程须用到的单元，心跳机制必用单元。-Winsock2.pas source, the development network programming unit to be used, the heartbeat mechanism must be used unit.

员工抽奖程序，使用闪烁属性，让抽奖很刺激，玩的很心跳，最多抽奖员工可大5000多人-Employees sweepstakes program, use of scintillation properties, very exciting sweepstakes, play the very heartbeat up lottery employees can be as large more than 5,000 people

将心电数据从文件中读取出来，并由声卡读入，从而发出心跳声，可将得到的声音作为模拟的心电信号(The ECG data is read out from the file and read by a sound card, so that the heartbeat sounds can be obtained, and the sound can be used as an analog ECG signa)

上位机使用LABVIEW显示心跳曲线， USB采集，单片机采用STM32F103C8，心跳检测芯片采用AD8232，利用单片机自身AD转换(The upper computer uses LabVIEW to display the heartbeat curve, USB to collect, SCM uses stm32f103c8, heartbeat detection chip uses ad8232, SCM uses its own ad conversion)
